Reorder output chain when subrequests are used

[Marat Dakota]

Ok, I need improper way then. Just some way.

The problem is that I know "bbb" only after the subrequest is made. And
subrequest's body is being completely filtered by body filter. So, in fact
I will not have "ccc", just "aaabbb", but I can't flush "bbb" out because
it waits for the subrequest to be done.
